In our ongoing experiments on the DESIRS beam-line at the SOLEIL Synchrotron, we are acquiring the necessary data on oscillator strengths and predissociation rates for modeling CO photochemistry in astronomical environments. A VUV Fourier Transform Spectrometer with a resolving power of about 350,000 allows us to discern individual lines in electronic transitions. Here we focus on results obtained from absorption spectra of $^{13}$C$^{18}$O, for the $W~^1Pi~-~X~^1Sigma^+$ bands with $v^{prime}=0, 2, {rm and} 3$ and $v^{primeprime}=0$ and three resolved bands involving transitions to the upper levels 4p$pi$(2), 5p$pi$(0), and 5p$sigma$(0) of the 4p(2) and 5p(0) complexes. We compare our results with earlier determinations for this isotopologue of CO, as well as with our SOLEIL measurements on $^{12}$C$^{16}$O, $^{13}$C$^{16}$O, and $^{12}$C$^{18}$O.
